Dynamic Application Security Testing (DAST) is an automated testing process designed to identify security vulnerabilities in a web application. It does this by simulating attacks on the application and analyzing the responses. Unlike static testing, which analyzes an application’s code, DAST tests the application’s functioning in real-time, making it an effective tool for securing live web applications.
DAST is a black-box testing method, meaning it does not have any knowledge about the internal structure of the application it’s testing. Instead, it examines the application from the outside, much like an attacker would.
